Thermo Scientific MaxQ 2000 Plus CO2-Resistant Orbital Shaker
The Thermo Scientific MaxQ 2000 Plus is a compact CO2-resistant orbital shaker designed for operation inside compatible CO2 incubators and other controlled environments where elevated humidity and CO2 concentrations make conventional laboratory shakers unsuitable. With a 30–300 rpm speed range, 19 mm orbital motion, magnetic drive system, and external controller, the MaxQ 2000 Plus provides a practical way to add orbital agitation to an existing incubator without purchasing a complete dedicated incubator shaker.
Available used and refurbished from American Instrument Exchange, this Thermo MaxQ 2000 Plus is inspected, cleaned, and tested prior to shipment. It includes a 90-day warranty from American Instrument Exchange.

Overview
The Thermo Scientific MaxQ 2000 Plus differs from a conventional benchtop orbital shaker because it is specifically engineered for operation in demanding CO2-rich and high-humidity environments. This makes it particularly useful for laboratories that need orbital shaking for suspension culture or other biological applications while maintaining samples inside an existing CO2 incubator.
The shaker mechanism is positioned inside the incubator while its control box remains outside the chamber. This arrangement allows users to adjust shaking speed and operating time without repeatedly opening the incubator door and disturbing temperature, CO2 concentration, or humidity.
Specially treated mechanical components provide resistance to the challenging environment inside a humidified CO2 incubator, while a magnetic drive eliminates traditional drive belts. Low heat dissipation also helps minimize the effect of the shaker on the incubator's temperature-controlled environment.

Platform, clamp, rack, and vessel configurations can vary among used shakers. Maximum vessel capacity should therefore be determined from the actual platform and accessories supplied with the individual unit rather than from a manufacturer's theoretical flask-capacity specification.
Common Applications
The MaxQ 2000 Plus is particularly well suited to laboratory workflows requiring orbital agitation within a temperature- and CO2-controlled environment. Applications can include mammalian suspension cell culture, shake-flask cell expansion, cell-line development, protein-expression research, media optimization, microcarrier research, bacterial suspensions, hybridization, washing, extraction, and other biological or general laboratory mixing procedures.
For cell culture applications, the shaker provides orbital motion while the surrounding incubator supplies the required temperature, humidity, and CO2 environment.
Ideal Laboratory Types
The Thermo MaxQ 2000 Plus is a useful option for biotechnology and biopharmaceutical laboratories, cell biology research groups, academic laboratories, university core facilities, pharmaceutical research laboratories, protein-expression facilities, cell and gene therapy research groups, and other laboratories working with suspension cultures.
It can be especially useful when a laboratory already owns a suitable CO2 incubator and wants to add shaking capability without investing in a complete dedicated CO2 incubator shaker.
CO2 Resistance & Shaking Performance
The MaxQ 2000 Plus operates from 30 to 300 rpm using a 19 mm orbital motion. The broad speed range allows shaking conditions to be adjusted according to vessel type, fill volume, cell line, sample requirements, and desired mixing intensity.
Unlike a conventional open-air shaker, the MaxQ 2000 Plus is designed for operation in environments containing up to 20% CO2 and relative humidity as high as 95%. Its mechanical components are treated to withstand these conditions, making it more appropriate for prolonged operation inside a humidified CO2 incubator.
The magnetic orbital drive eliminates conventional drive belts, reducing the number of mechanical wear components. Thermo also designed the shaker for low heat dissipation, an important consideration when placing powered equipment inside a temperature-controlled incubator.
Platform, Flask & Vessel Compatibility
The compact MaxQ 2000 Plus can accommodate a variety of laboratory vessels when equipped with an appropriate platform, clamps, racks, or other accessories. However, practical vessel capacity depends heavily on the exact platform configuration, flask or vessel dimensions, clamp arrangement, liquid volume, and available vertical and horizontal clearance inside the incubator.
For this reason, flask counts or vessel capacities published for a particular factory configuration should not automatically be assumed to apply to every used MaxQ 2000 Plus.
American Instrument Exchange can confirm the platform and accessories included with the specific unit being purchased. Customers planning to use particular flasks, bottles, culture vessels, or custom platform arrangements should verify compatibility before ordering.
Refurbishment & Testing
This used Thermo Scientific MaxQ 2000 Plus is inspected and tested by American Instrument Exchange prior to shipment. Evaluation includes verification of orbital drive operation, speed adjustment, timer function, controller response, display operation, and overall mechanical and electrical condition.
The equipment is also cleaned and prepared for laboratory use. Customers with application-specific testing requirements are encouraged to discuss those requirements with American Instrument Exchange prior to shipment so that appropriate functional testing can be performed whenever practical.
Shipping & Installation
The MaxQ 2000 Plus shaker mechanism measures approximately 14.2 inches wide by 11.8 inches deep by 3.8 inches high, giving it a compact footprint for installation inside compatible incubators.
Before installation, laboratories should verify the incubator's usable internal dimensions, available vessel height, platform clearance, electrical access, shelf or mounting load limits, and airflow requirements. The shaker and vessels should not interfere with incubator sensors, airflow passages, drains, humidity systems, or other components required for proper environmental control.
The external controller remains outside the incubator, allowing users to monitor and adjust shaking operation without unnecessarily opening the chamber.
The MaxQ 2000 Plus is a compact orbital shaker specifically designed for operation inside compatible CO2 incubators and other high-humidity controlled environments.
Does the MaxQ 2000 Plus control CO2 or temperature?
No. The MaxQ 2000 Plus provides orbital shaking only. Temperature, CO2 concentration, and humidity must be controlled by the surrounding incubator or environmental chamber.
What is the speed range of the MaxQ 2000 Plus?
The shaker operates from 30 to 300 rpm with a 19 mm / 0.75-inch orbit.
Why is the MaxQ 2000 Plus suitable for a CO2 incubator?
The shaker is designed to withstand environments containing up to 20% CO2 and high relative humidity. It also uses an external controller and is designed for low heat dissipation, helping reduce disturbances to the controlled incubator environment.
What is the maximum load capacity?
The MaxQ 2000 Plus has a maximum rated load of approximately 13 lb / 6 kg. This is a weight specification rather than a guarantee that a particular number or size of flasks will fit on an individual unit.
How many flasks will fit on the MaxQ 2000 Plus?
Actual flask capacity depends on the installed platform, clamps or accessories, vessel dimensions, flask arrangement, and available clearance inside the incubator. Because used units may have different or custom platform configurations, customers should confirm the configuration of the specific shaker before purchase.
Does the MaxQ 2000 Plus use a drive belt?
No. The MaxQ 2000 Plus uses a magnetic orbital drive, eliminating the conventional drive belt found in many laboratory shakers.
Can the MaxQ 2000 Plus be used outside a CO2 incubator?
Yes. Although its CO2-resistant construction makes it particularly useful inside compatible incubators, it can also provide orbital shaking for appropriate applications outside a CO2 environment.
Does this refurbished MaxQ 2000 Plus include a warranty?
Yes. This used and refurbished Thermo Scientific MaxQ 2000 Plus includes a 90-day warranty from American Instrument Exchange.
